To be fair, I'm not completely sold it doesn't belong on 305. after seeing the video and the still it backs up things said in the past. I'm pretty sure it wasn't on 305. many have made similar claims, including myself about the condition of the placard. wind, movement have all be discussed. it is strange to believe it sat where it landed for almost 8 years without moving or being overgrown. it's very light, extremely light. Hicks claims it was in some brush.
Points are brought up about the placard. it's an interior placard. typically, they remain in the interior. I agree completely. I question how this could be anything but from a plane with the stairs down. it's really hard to disprove. perhaps our hunter punked us all. I don't think it would be hard for Hicks to find the flight path or the general area, even in 1978.
A certain amount of planes the same series or 100's had kits that could be purchased from Boeing and installed on them. they could be no different than the one's we see in the photo's over the years having this option. I don't know.
Northwest confirms the placard comes from the same type of plane but fail to confirm they had the system installed. it's very frustrating getting half the answers all the time.
